Given :
The vertices of parallelogram ABCD are A(4,0,3), B(3,4,-2),C(-2,0,1).
To Find :
The coordinates of fourth vertices.
Solution :
We know, the vertices are ABCD .
Let, point D is (x,y,z) .
Also, diagonals of a parallelogram bisect each other.
Let, point of intersection of daigonal is O.
Coordinates of O are :
O(1,0,2)
Value of point O through BD.
Therefore, the fourth vertices is D( -1,-4,6 ).
Answer:
194
Step-by-step explanation:
Recall 2 rules to solve this easily:
1.
2.
<em>Now, if we let a = 7 and , we can say the problem is basically of the form:</em>
This can be simplified using the rules:
Now we can plug the values of a and b we initially thought of (remember though ):
194 is the final answer.
